Waste water in hole, which is transported in oil water separator, carries out water-oil separating, and the waste water after separation, which enters in anaerobic fermentation reactor, to ferment
Biogas is generated, the waste oil of separation enters in biodiesel reaction kettle, and fermentation generation biogas enters combustion gas in anaerobic fermentation reactor
It burns in boiler, the steam that gas fired-boiler generates is made to be transported in Sterilization Kettle and drier, the solids that dewatering centrifuge generates
It is transported in drier by conveyer, the weary steam in Sterilization Kettle and drier is laggard by steam condenser and softening water tank
Enter gas fired-boiler.
The outlet of embodiment as one preferred, biodiesel reaction kettle is connect with biodiesel rectifying tower, biological bavin
The outlet of oil rectifier is connect by condenser with product receiving tank.
The outlet of embodiment as one preferred, drier is connect by conveyer with packing machine, is generated in drier
Dust be provided with clinker groove by being discharged after cyclone dust collectors air-introduced machine and deodorization device, on the downside of cyclone dust collectors.
Embodiment as one preferred is connected with cooling tower on steam condenser.
Embodiment as one preferred, kitchen garbage are transported to Sterilization Kettle after crusher by feedstock transportation pump
In.
It is had the beneficial effect that using what the above-mentioned technical proposal present invention obtained：After kitchen waste crosses sorting crushing, passing through
Propose oily recycling, by oil recovery therein, and after through entering anaerobic fermentation reactor, under certain circumstances, by hydrolysis acid
Change, methanation generation biogas, biogas is used as fuel after purification, and biogas slurry and biogas residue are used for rural power, in biogas production process
It not can cause environmental pollution, but also alleviate energy crisis.
